- getBtcRates()/useBtcRates() read every BTC→fiat rate from the ONE Coinbase exchange-rates call the app already made, plus sats (1e8). No new endpoint. - The calculator's currency control is now a searchable Popover: sats + every fiat Coinbase reports, with a search box. Selecting a currency CONVERTS every money field (labour, rent, utilities, subscriptions, equipment cost, material order/shipping, packaging materials) by the live ratio; unitless fields (overhead factor, board counts, minutes, margins) are untouched. Falls back to relabel-only if rates aren't loaded. - Currency symbols/formats for the common fiats.
